v3.1.0

3.1.0

• 🚀 Feat: The debug modus now shows the current FPS.
• 🚀 Feat: isTouchingSprite(Class). IsTouchingSprite accepts also a Class, so you can check the collision with all objects of this class.

v3.0.0

3.0.0

Scratch for Java will from now on focus on being a standalone library. Even though it can be used in processing.

We also provide os-specific jar files for the standalone version.

v2.1.0

Changes

• 🚀 Feat: Image, Text and Pen can now be added without being used in a Sprite. Example:

import org.openpatch.scratch.Stage;
import org.openpatch.scratch.extensions.Pen;

public class PenStandalone {
    public static void main(String[] args) {
        Stage s = new Stage(400, 400);
        Pen p = new Pen();
        p.down();
        p.setPosition(40, 40);
        p.setPosition(40, 100);
    }
}

• 🚀 Feat: AnimatedSprite and Sprite now support SpriteSheets. Example:

import org.openpatch.scratch.AnimatedSprite;
import org.openpatch.scratch.Stage;

public class SpriteSheet {
    public static void main(String[] args) {
       Stage stage = new Stage() ;
       stage.add(new AnimatedBee());
    }
}

class AnimatedBee extends AnimatedSprite {
    public AnimatedBee() {
        this.addAnimation("idle", "bee_idle.png", 6, 36, 34);
    }

    public void run() {
        this.playAnimation("idle");
    }
}

• 🐛 Fix: Pen did not include the first point

BREAKING CHANGES

• 💥 Prefix Scratch is removed. For exmaple: ScratchSprite -> Sprite, ScratchStage -> Stage
• 💥 getInstance and init got removed from Stage. You now have to instantiate a Stage like a normal Object new Stage(this) // Processing or new Stage(400, 400) // Standalone. Be aware that you can only have one Stage at a time.

v2.0.0

The Processing library Scratch changed owners. It is now hosted under the OpenPatch organization, therefore the package name change. You can now access the classes of this library like so:

import org.openpatch.scratch.*

v1.15.0

The Standalone Release

This release does not change the behaviour of the Processing library!

You can now use the scratch-standalone.jar for using this library in any Java environment. When you use this library outside of processing, you have to create a new object of the class ScratchStage. The init-method will only work in Processing.

import eu.barkmin.processing.scratch.*;

public class MyProgram
{
    public MyProgram() {
        ScratchStage s = new ScratchStage(800, 400);
        s.addSprite(new Cat());   
    }
}

class Cat extends ScratchSprite
{
  public Cat() {
    this.addCostume("sitzen", "sprites/cat.png");
    this.setOnEdgeBounce(true);
  }
  
  public void run() {
      this.move(1);
  }
}

You can also use this library outside of Processing in a more imperative way, similar to Shapes and Sprites. For this to work, the wait-method was added to the ScratchStage class.

import eu.barkmin.processing.scratch.*;

public class MyProgram
{
    public MyProgram() {
        ScratchStage s = new ScratchStage(400, 400);
        ScratchSprite cat = new ScratchSprite(
            "sitzen", "sprites/cat.png"
        );
        s.addSprite(cat);
        
        cat.setOnEdgeBounce(true);
        
        while(!s.isKeyPressed(27)) {
            cat.move(1);
            s.wait(100);
        }
    }
}
